Answer:
The correct anser is option
B. 2x + 2 = 18
Step-by-step explanation:
Let the number of hot dogs eaten by the runner up be represented by x
If Dave ate 2 more than twice x, this means that the number eaten by him = 2x + 2
Since the total number of hot dogs eaten by Dave is 18
Therefore, the equation will be
2x + 2 = 18
So the number of hot dogs eaten by the runner-up is determined by solving for x
2x= 18-2
2× = 16
x = 16/2
x = 8
The runner up are 8
While Dave are
2×8 + 2 = 18.
Answer: $ 200,000
Step-by-step explanation: The 6000 is 3% of the original price, so 6000/3 = x/100. To find the price of the home we will need to cross multiply and divide.
6000/3 = x/100
6000 * 100 = 600000
600000 / 3 = 200,000
Answer:
3
Step-by-step explanation:
gradient/slope/m formula:-
(-6,2) (4,10).
m=(10-4)/(-4-6)
m=6/2
m=3
7x³-7x²
You have to divide each by the greatest common factor. In this case that is 7x²
So now you have 7x²(x+1). Now you set each factor to 0
x+1=0
x=-1
and
7x²=0
x=0
Your answers are x=-1 and x=0
